Background
Born August 18, 1987 in Olsztyn, Poland. Jędrzejczyk discovered Muay Thai as a teenager and quickly became one of Poland's most accomplished combat sports athletes. She amassed an extraordinary kickboxing and Muay Thai resume — 37 wins, three losses, six IFMA World Muay Thai Championship medals (five gold), four IFMA European Championships, and multiple World Kickboxing Network and World Muaythai Council titles — before transitioning to professional MMA in 2012.
She went undefeated in her first six MMA fights across European promotions and signed with the UFC in July 2014. She made her UFC debut at UFC on Fox: Lawler vs Brown in July 2014 with a unanimous-decision win over Juliana Lima. Two fights later — at UFC 185 in March 2015 — she dethroned inaugural UFC strawweight champion Carla Esparza by second-round TKO to become the first Polish UFC titleholder and the first female European UFC champion. She trained at American Top Team in Coconut Creek, Florida from her UFC 205 camp onward and now resides in Poland.
Fighting Style
Pure championship-level Muay Thai and kickboxing built on a 37-3 professional Muay Thai record and six IFMA World Championship medals. Jędrzejczyk's pattern was textbook footwork and distance management combined with high-volume punching, low-kick attacks, and elite takedown defense — the highest takedown defense rate in UFC women's strawweight history. MMA analysts have repeatedly compared her striking foundation to Jose Aldo and Chuck Liddell — fundamentals-first, distance-first, damage-first.
Her weakness — exposed only in two distinct championship-era moments — was the cumulative cost of fighting at high pace against equally skilled strikers. Rose Namajunas's UFC 217 first-round TKO in 2017 ended the title reign in a single shot; Zhang Weili's UFC 248 split-decision war in 2020 produced the greatest women's MMA fight in history; the UFC 275 spinning-backfist KO in 2022 produced her retirement fight. Within her championship window from 2015 to 2017, however, no one in the strawweight division could solve her game. The five-defense title reign and the +142 significant-strike differential record (her UFC 211 defense vs Jessica Andrade) remain the canonical women's strawweight benchmarks.

Notable Fights & Rivalries
vs Zhang Weili (UFC 248 2020, UFC 275 2022)
Two fights, two Zhang wins, but the first is the greatest women's MMA fight in history. The UFC 248 split decision in March 2020 saw both fighters land over 150 significant strikes in a five-round war that won every Fight of the Year award given out in 2020 and was inducted into the UFC Hall of Fame's Fight Wing in March 2026 during the UFC 326 broadcast. The rematch at UFC 275 in June 2022 was a more decisive Zhang spinning-backfist KO at 2:28 of round two — the bout Joanna retired from.
vs Rose Namajunas (UFC 217 2017, UFC 223 2018)
Two fights, two Namajunas wins. Namajunas knocked out Joanna at UFC 217 in November 2017 in a first-round TKO that ended Joanna's two-and-a-half-year championship reign — one of the biggest upsets in women's MMA history. The rematch at UFC 223 in April 2018 was a more competitive five-round unanimous decision for Namajunas. The two losses prompted Joanna's brief move to flyweight.
vs Claudia Gadelha (UFC on Fox 13 2014, UFC 200 2016)
Two fights, two Joanna wins. The first was a controversial split decision at UFC on Fox 13 in December 2014 that the majority of MMA media scored for Gadelha; the rematch at UFC 200 in July 2016 was a five-round unanimous decision for Joanna — her third successful title defense. The two coached opposite each other on The Ultimate Fighter Season 23 between the bouts.
vs Carla Esparza (UFC 185, 2015)
The fight that crowned Joanna as UFC women's strawweight champion. She stopped Esparza — the inaugural UFC strawweight champion — at UFC 185 on March 14, 2015 by second-round TKO to become the first Polish UFC titleholder and the first female European UFC champion. The result is one of the canonical examples of striker-vs-grappler championship-level dominance.
vs Jessica Andrade (UFC 211, 2017)
Joanna's fifth and final successful title defense. She outstruck Andrade by a +142 significant-strike differential across five rounds in a unanimous-decision win — the highest significant-strike differential in UFC women's championship-fight history at the time. The result confirmed her championship-level dominance at strawweight had no answer in the division through that period.

Legacy / Verdict
Joanna Jędrzejczyk is the most accomplished strawweight in UFC history and one of the foundational figures of women's MMA. The five-defense championship reign — Penne, Letourneau, Gadelha, Kowalkiewicz, Andrade — remains the canonical UFC women's strawweight resume. Her +142 significant-strike differential at UFC 211 against Andrade is a UFC women's championship-fight record that may never be broken; the eight-fight UFC strawweight winning streak is another division record. The 2024 Modern Wing UFC Hall of Fame induction was a near-instant acknowledgment of unimpeachable championship credentials.
What complicates the legacy is the four-fight title-loss stretch in her late career — both Namajunas losses, the Shevchenko flyweight loss, and the two Zhang losses — which capped the championship reign at one and ended her competitive title chances. The post-retirement chapters (the Hall of Fame Modern Wing, the additional Fight Wing induction in 2026, the comedy career, the foundation, the rally driving) frame the full story: Joanna is the answer to "greatest UFC women's strawweight ever" and one of the top three or four foundational figures of women's MMA in the modern era. The legacy is permanent.
